I wish I had that part number from when I did it...

I believe its an M12 but dont remember the pitch. Just take your factory one w/ you and swing by Lowe's... they have those fitment guides there to test it out.. thats how I found mine...

^^yep^^ Or go to a local Advance Auto or any auto parts store. They have thread sizers there as well. Then, if possible, go to a local hardware store. I have had better luck at the local place for Stainless and capheads than at the big box places.

8mm x 1.25. These allen head bolts typically are 6mm. I had to get a set for a dellorto once upon a time.
